		The yaw angle rotates around the z axis, the pitch angle rotates aroud the new y axis, and the roll angle
		rotates around the new x axis.

		In case of 6 DoF support for rendering, the head rotation trajectory file may also include a listener
		position in absolute Cartesian coordinates on the x-, y- and z-axis. Note that the listener position is
		expressed in absolute coordinates, while the listener orientation is expressed as scene displacement.
		An example line from a headtracking file of a listener facing forward, positioned at x=3.0, y=4.0 and z=0,
		could be:

		-3.0,0.0,0.0,0.0,3.0,4.0,0.0

		Note that the listener position applies for listener orientation expressed both in Quaternions and Euler angles.


		For the Head rotation operation modes, external trajectory files are available:
